Balance has never been an issue for him. This happened suddenly and after his dosage was increased. I've also noticed a change in the way he talks, i.e., slurring his words just a little. He says he feels fine otherwise. He has a physical coming up in about 10 days but I really don't want to wait for that. Also, has anyone had experience changing from a GP to a Geriatric Physician? I'm not at all happy with his GP and am thinking about making a change.
